Application filed October 21, 1919.- Serial No. 332,338.

To all whom it may concern."

Be it known that we, Nuns B. ANDERSON and JOSEPH A. BERG, citizens of the United States, and residents of the city of Astoria, county 6f Clatsop, State of Oregon, have invented certain new and useful Improvements in Can Salters, of which the following is-a specification.

Our inventlon relates to appliances having for their purpose the supplying of a fixed amount of a granular material, such as T e particular purpose for which this device has been designed is the supplying of the salt required to cans which are intended for thereception of fish prior to scaling." The specific object of this invention is to provide a device of this character in the use of which a blast of air is employed to insure the delivery of the salt into the can.

In the accompanying drawings .we have shown our preferred construction, and the same will be hereinafter specifically described. The features of our invention which we deem to be new and upon which we desire patent protection will be defined in the claims terminating this specification.

Figure 1 ,is a side view of our device showing its relationship to an incline, over which the cans are passed prior to being filled, and a can-feed controlling mechanism.

Figure 2 is a top or plan view of the same parts. I

Figure 3 is a vertical section taken through the central axis of the device, the'air pump.

and its connections being diagrammatically illustrated.

Figures 4 and 5 are plan views taken on a plane just above the rotary disk by which the supply of salt for the individual charges is delivered to the conveying chute. I

In the drawings 1 represents a tank or container for a quantity of salt. Thisis provided with a bottom having openings, as 10, through which the salt may pass, and thus have contact with the rotatlng measuring plate 2. This tank 1 is supported in fixed;

positlon.

Immediately below. the tank 1 is the measuring plate 2, which is mounted for rotation in a horizontal plane. The plate 2 is provided with holes 20, of a size to contain the amount of salt which it is desired to deliver to each individual container. Provision is ing made whereby the plate 2 is given an intermittent rotation, thereby placing each one of the holes 20 in succession over a disc arge opening 30 in a base plate 3, upon whi the measuring plate 2 is mounted. This discharge opening 30- is beneath a portion of the bottom 11 of the tank which is not comprised within the openings 10. Communicat, ing with the discharge openin 30 is a discharge chute or pipe 31, the ischarge end of which is horizontally directed, or the end of which may be bent toform a horizontallyextending nozzle, as may be desired.

We have shown, in conjunction with this "device, a trapway or runway 4, over which Patented May 16,1922.

The means illustrated for this purpose comprises a star wheel 42 having recesses for the receptionof individual cans as they are delivered from the incline 4, and rotatable bymeans of an intermittently, oscillate "with'the ratchet wheel 45 upon the same shaft as the star wheel 42. Motion is given to the arm 43 by means of a link 46 and an arm 47,. which is connected with arm 62 or arm '43 carrying a dog 44 engageable;

any other part which is oscillated therefrom,"

as lever- 6, and these are actuated through a link 63 from a lever 64 which is pivoted at 66"-and carries cam rollers or followers 65 and 68, the latter carried on an extension arm 67. A cam 69 acts to swing lever 64 at regular intervals thus oscillating the feed for the feed disk 2 and that for thecan spider 42.

The bottom of the tank 1 is provided with a boss 12 which is chambered at its lower side to correspond substantially'with one of the measureopenings 20 in the plate 2 when the plate is in sition of rest. Communicating with the c amber in this boss 12, is an air conveying pipe 5. This pipe is in communication with any source of supply of air unthrough the pipe 5 at intervals, and these v w o intervals are timed to correspond .withthe delivery of a charge of salt to the chute 31 by the proper positioning of the plate 2.

It is evident that if the plate 2 be positioned so that the feeding compartments 20 therein are in register, both with the discharge openings in the base 3 and also with the air chamber formed in the boss 12,

and air under pressure be admitted to such chamber, this air will blow all of the salt contained in the compartment 20, and also in the. chute 31, from the discharge end of the feed chute, and if at this time a can be positioned before the opening of the chute 31 with its open end in line therewith, this salt will be delivered horizontally into the can.

The means for controlling the blast of air is herein shown as consisting of a pump cylinder 50, havin therein a piston 51, which may be operated in any convenient manner, either independent of or in connect-ion with some member of themachine which will give it a sufficient stroke at the time desired. It

is also evident that this air supply connec tion maybe with a tank containing air under pressure, and the controlling mechanism consists of a valve which is automatically actuated and properly timed through mechanism of any suitable character.

The means illustrated for securing this comprises a pump having its piston 51 operatively connected with a lever 52 pivoted:

at 53 and oscillated at regular intervals by a cam 54: acting upon the ollower 55.

The means provided for rotating the feed I disk 2, as herein illustrated, conslst of the following: The disk 2 is provided with a se ries of projections or teeth 21, the same corresponding in number with the number of measuring compartments 20. A pawl-carbeing pivoted upon a fixed pivot at the point 70. The end 71 of this do the periphery of the disk 2.

extends over ecured to turn 3 with the arm 7 is another arm 72, this being positioned to be engaged by a short arm 64, which is carried by, or moved in conformity with, the arm 6, which carries the feeding pawl 60. These arms 64 and 72 are so positioned that when the arm 6 is withdrawn, in order to engage another one of the projections or teeth 21, the stop dog will be forced outwardly enough to permit free turning of the disk 2.

On the forward or feeding movement of 21 which is just in front of it and move the disk 2 a sufficient amount to pass the engaging end 71 of the retaining dog, and thus permit the wheel to be moved one tooth space. In the advance movement of the arm 6 the finger 64 will be moved so as to permit the retaining dog 7 to swing inward into engagement with the disk and thus to insure stoppage of the disk 2 when the feed compartment 20 gets into exact registry with the discharge opening 30. A

spring, or an equivalent member, as 73, is-

employed for insuring the return movement of the locking dog 7.

In order to insure close contact between the bottom of the tank .1 and the feeding plate 2, without probability of binding the same, a spring 8 is employed for holding the tank down upon the plate. The tank is mounted about a central bar 13 and the spring 8 is placed about this bar. A washer as 80, which is secured to the upper end of v the .bar 13, takes the thrust of the spring.

A tube 9 is secured in the boss 12, which contains the air chamber and in alinement with the receivin end of the discharge chute 31. This is provided with a cap 90, or other means by which its upper end may normally be closed, By the use of this device it is possible, if this at' any time be necessary, to employ a rod for dislodging any particles of salt which may become caked in the feed compartment or in the feed chute.

In operating the device the disk 2 is given an intermittent movement by the pawls 60 and 7 as described, or by an equivalent device. The salt is thus delivered in measured quantity to the feed chute. At the time the feed plate is brought into proper position for the discharge of salt, the air is supplied through the pipe 5, thus furnishing a blast for the prompt removal of the salt.

The device is so constructed as to be simple to manufacture and to be easily taken care of'and inspected. Its operation is such as to also secure reliability. The use of air pressure in connection with a mechanical feeder insures a prompt and complete delivery of the salt, and also 'makes it possible to deliver the salt into cansplaced in position such that the reliable delivery of the salt by other means might be very difiicult, if not impossible. By combining a pneumatic delivery with a mechanical feed, reliable and certain action is secured and the device is adaptable to use with apparatus for the handling of the cans which vary widely in their construction and principle of action.
